FRANK R. WOODWARD, OF HILL, NEW HAMPSHIRE, ASSIGNOR OF ONE-HALF TO SMITH& I-IEZMENWAY COMPANY, INCORPORATED, OF NEW YORK, N. Y. 1

GLASS-CUTTER.

mack and State of New Hampshire, have invented certain new and usefulImprovements in Glass-Cutters, of which the following is aspecification.

This invention relates to certain new and useful improvements in glasscutters, of that class of cutter employing a rotary cutter wheel, andmeans for lubricating the cutting wheel when the same is in operation;the object being to improve the general'construction of this class ofcutter, and to provide the head thereof with means for retaining anumber of extra cutter wheels which can be readily removed in order toreplace a cutter when the same wears out.

Another object of my invention is to improve the general construction oflubricating means for the cutter to provide means for retaining theabsorbent material in such a manner that a greater quantity of materialcan be used in order to obtain a cutter wheel which will not have to bedipped in oil as often as is the case with cutters of this character nowin use.

A further object of the invention is to provide novel means forretaining the cutter wheels in the retaining pockets and for holding thebearing pin of the cutting wheel in position.

Other and further objects and advantages of the invention will behereinafter set forth and the novel features thereof defined by theappended claims.

In the drawings-Figure 1, is a side elevation of a glass cutterconstructed in accordance with my invention, the handle being partlybroken away; Fig. 2, is a top plan view of the same; Fig. 3, is asection taken on the line 3-3 of Fig. 1; Fig. 1, is a side elevation ofa modified form of cutter, the handle being broken away; Fig. 5, is atop plan view of the same, partly broken away; Fig. 6, is a sectiontaken on the line 6-6 of Fig. 5; Fig. 7, is a side elevation of stillanother modified form of cutter partly broken away; and Fig. 8, is asection taken on the line 8-8 of Fig. 7.

In Figs. 1, 2 and 3, I provide a head 1 of the usual shape having a cutaway portion 2, in which is arranged a cutter wheel 3 mounted upon abearing 4 secured in open- Specification of Letters Patent.

ings 5 formed in the opposite sides of the cut away portion, as clearlyshown, said bearing being of a length so that the ends thereof will beflush with the side walls of the head. lhe head is provided with theusual shank 6 which is secured in the handle 7 in the ordinary manner,and one side of the head is provided with a series of pockets orrecesses 8 communicating with each other, by grooves 9 in which isarranged packing material 10, said pockets being adapted to receiveeXtra cutter wheels 11, the forward pocket being provided with a groove12 extending into the cut away portion 2 and is likewise filled with thepacking material 13. Packing material or absorbent material 14% isarranged in the cut-away portion 2 of the head, and contacts with thewheel 3 and it will be seen that by dipping the head in oil, the packingmaterial will absorb the oil and apply the same to the cutter wheel, asthe same is in use. The pockets form reservoirs which will retain acertain amount of oil besides the cutter wheels, so as to pro vide alubricating device which will lubricate the cutting wheels for a greaterlength of time than with glass cutters of this character now in use. Inthis form, the head is preferably formed of sections, but I do not limitmyself to this construction, as the same could be formed of a solidhead.

In order to provide means for closing the pockets and grooves, and formaintaining the journal of the cutter wheel in position, so that thesame is prevented from moving laterally in the direction it is inserted,I provide the head with a pivotally mounted member 15 which normally isheld in position overthe pockets, by friction. the end thereof extendingover the journal so that the same is held securely in position. Byswinging the member 15 to one side, the journal can be forced outwardlyin that direction. so as to remove the cutter wheel when desired.

In Figs. 4 and 5, I provide a head 16 constructed in this instance, of asolid member having a shank which is secured within a handle 17 in theordinary manner, the upper edge of said head being provided with alongitudinal groove 18 which communicates with a cut away portion 19formed in the end thereof whereby the head is provided. with abifurcated end in which is mounted Patented Feb. 23, 1915.

Application filed August 21, 1912. Serial No; 716,231.

a cutter wheel 20 on a journal pin 21 the 16 same have been dipped intoa can of oil in order to thoroughly saturate the same. The groove-inthis instance, forms a pocket in which a number of cutter wheels can bearranged, and over which the absorbent or packing material is arranged,forming a. reservoir which will retain a certain amount of oil so as tothoroughly lubricate the cutter wheel when in use.

For holding the packing material in position within the groove, and toprovide means for preventing the journal 21 from moving in the directionin which it is inserted, in the openings of the bifurcation, I providethe head with a pivotally mounted member 28, the forward end thereofextending over the end of the journal 21 and the rear end is providedwith a lateral projection 24 which extends over the groove 18, andmaintains the cutter wheel in proper position. In this construction, itwill be seen that alubricating glass cutter is formed which isexceedingly simple and cheap in construction, and one in which thecutter wheel can be easily and quickly removed by simply swinging thepivotally mounted member outwardly as shown, in dotted lines in Fig. 4,to allow the journal pin to be moved laterally so as to disengage thecutter therefrom, whereby a new cutter may be readily installed asdesired. It will also be seen that the pivotally mounted membermaintains a portion of the absorbent material in position as well as thecutter wheels arranged thereunder, and while I have shown the grooveextending to the bifurcation it is of course understood that a passagewith a closed top can be formed for forming a communication between thegroove and the bifurcation in order to receive a wick in order to applylubricant to the cutter wheel.

In Figs. 7 and 8, I show still another modified form of cutter wheel inwhich the head 25 is also provide with a bifurcated end 26 whichcommunicates with a groove 27 formed in the top of the head in which anumber of auxiliary cutter wheels 28 can be placed so as to have theextra cutter wheel handy at all times; said cutter wheels being retainedin their proper positions by a strip of packing material 29 whichextends the entire length of the groove and contacts with the cutterwheel 30 arranged in the bifurcation of the head; said cutter wheelbeing mounted on a pivot 31 which is provided with a yoke portion 32extending rearwardly-and adapted to straddle the head and maintain theabsorbent material over the cutter wheels, as clearly shown in Fig. 7.By this construction, the cutter wheel can also be readily detached asthe pivot can be swung outwardly and then drawn laterally so as toremove the cutter wheel therefrom, and when forced into the position asshown in Fig. 7, it will be 1naintained in position by frictionalcontact with the side walls of the head. As shown in Fig. 7, the groovein the head forms a retaining pocket for additional. wheels, and also areservoir to retain oil after the same has been forced in a can oflubricant, whereby the wheels will be prevented from rusting and at thesame time a larger amount of oil is provided to be absorbed by thepacking material which contacts with the cutting wheel in operation, soas to thoroughly lubricate the same.

From the foregoing description, it will be seen that I have provided aglass cutter with an auxiliary wheel retaining pocket which also forms areservoir for oil, which is supplied directly to the cutting wheel inoperation, by absorbent or packing material. It will also be seen thatby this construction, an ordinary glass cutter now in use, can bereadily provided with my improved construction in order to form meansfor carrying a number of cutting wheels thereby and for applyinglubricant to the cutting wheel in operation.

I claim:

1. A glass cutter comprising a head having a cutter wheel at one endthereof, said head being provided with a pocket to receive an auxiliarycutter wheel, and absorbent material extending from said pocket to thecutting wheel thereof for lubricating said wheel when in operation.

2. A glass cutter, having a head provided with an auxiliary wheelpocket, a cutter wheel mounted in said head, absorbent materialextending from said pocket to said cutter wheel, and a pivotally mountedmember carried by said cutter for maintaining a cutter wheel within saidpocket.
